However, a sufficiently fast and accuratecomputation of global illumination at interactive rates has been difficult even with recent approaches based onrealtime ray tracing.<\/jats:italic> <\/jats:p><jats:p> <jats:italic>In this paper we present a highly scalable approach to interactive global illumination. It fully recomputes a high\u2010qualitysolution for each frame and thus offers immediate feedback even for dynamic scenes, achieving more than20 fps for simple scenes. Compared to previous systems we increased the raw performance by a factor of up toeight and removed the bottlenecks that were limiting scalability. The system now scales linearly in quality andavailable computing resources, tested with up to 48 CPUs in a commodity PC\u2010cluster. Due to its logarithmicscaling property with respect to scene complexity it even supports lighting simulation in complex scenes with morethan 50 million triangles. This scalability allows applications to perform flexible performance trade\u2010offs. We alsoargue that the realism achievable through interactive global illumination will make it a standard feature of future3D graphics systems once the required computing resources are readily available.<\/jats:italic> <\/jats:p>","DOI":"10.1111\/1467-8659.t01-2-00710","type":"journal-article","created":{"date-parts":[[2003,11,4]],"date-time":"2003-11-04T18:30:59Z","timestamp":1067970659000},"page":"621-630","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["A Scalable Approach to Interactive Global Illumination"],"prefix":"10.1111","volume":"22","author":[{"given":"Carsten","family":"Benthin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ingo","family":"Wald","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Slusallek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2003,11,4]]},"reference":[{"key":"e_1_2_7_2_2","volume-title":"AMD Technical Resources","author":"AMD Corporation"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/336414.336417"},{"key":"e_1_2_7_4_2","volume-title":"SIGGRAPH 2001 Course Notes, Course 40","author":"Chalmers Alan","year":"2001"},{"key":"e_1_2_7_5_2","first-page":"21","volume-title":"Rendering Techniques 2002","author":"Dmitriev Kirill","year":"2002"},{"key":"e_1_2_7_6_2","first-page":"57","volume-title":"Computer Graphics","author":"Drettakis George","year":"1997"},{"key":"e_1_2_7_7_2","volume-title":"Texturing and Modeling \u2014 A Procedural Approach","author":"Ebert David","year":"1998"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8659.00507"},{"key":"e_1_2_7_9_2","volume-title":"Intel Pentium 4 Processors Manuals","author":"Intel Corporation"},{"key":"e_1_2_7_10_2","first-page":"21","volume-title":"Rendering Techniques 1996","author":"Jensen Henrik Wann","year":"1996"},{"key":"e_1_2_7_11_2","first-page":"49","volume-title":"Computer Graphics","author":"Keller Alexander","year":"1997"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-7091-6242-2_25"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8659.00706"},{"key":"e_1_2_7_14_2","volume-title":"Proceedings of BRL\u2010CAD Symposium '95","author":"Muuss Michael J.","year":"1995"},{"key":"e_1_2_7_15_2","first-page":"119","volume-title":"Proceedings of Interactive 3D Graphics (13D)","author":"Parker Steven","year":"1999"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1145\/566654.566640"},{"key":"e_1_2_7_17_2","first-page":"27","volume-title":"Proceedings of Eurographics Workshop on Graphics Hardware","author":"Schmittler J\u00f6rg","year":"2002"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1145\/566654.566613"},{"key":"e_1_2_7_19_2","unstructured":"IngoWald CarstenBenthin andPhilippSlusallek.OpenRT \u2014 A Flexible and Scalable Rendering Engine for Interactive 3D Graphics.
